Through this question I wanted to know the original works of Galois. When I was reading Galois theory ( since from last month ) , I have been seeing one common line in every book, whose essence appears as follows :
" The original work of Galois is rather different from the presented version here ( which is due to Artin ) , the original works of Galois are different since the concepts like automorphisms and other things were not discovered at the time of Galois. "
I am curious to know what are the notions that Galois used ? , and what is the corresponding formulation of Galois theory, ( corresponding to the present version now which uses the modern vocabulary of Automorphisms ) .
But on the other hand , is there any complete biographical sketch of Évariste Galois ? . But I really wanted to know about him, I think there is not a single original picture of him. But there was an original photograph of Master Gauss with me ( but I don't have a original picture of Galois, rather than the portrait drawn by his friend and I would be much happy if someone gives a link to any rare picture other than the normal ones ).
